PORTSMOUTH — After a day of conflicting news and information, Portsmouth police officially report there are no ties between an abandoned vehicle recovered behind the local Walmart and the case of a missing child in Westminster, Colo. The vehicle has been returned to its proper owner, and is no longer considered a part of an ongoing investigation in the search for 10-year-old Jessica Ridgeway.Jessica reportedly went missing in her hometown of Westminster, Colo. on Oct. 5. The Associated Press reports local authorities there are investigating the incident as a child abduction. Ridgeway's mother says she last saw her child when she left home to walk to school.Portsmouth Police Sgt. David Keaveny told Foster's a tip came from a “concerned citizen” in Dexter, Maine, who phoned the local police department there, reporting the spotting of a blue station wagon with a little girl inside near a convenience store earlier this week. The caller believed the child to be the missing Colorado girl. At approximately 8:30 a.m. Thursday morning, Portsmouth police impounded a blue Buick station wagon, with Colorado license plates, which they found parked on Constitution Avenue, behind the Walmart on Lafayette Road. Deputy Chief Corey McDonald said officers treated the area as a “crime scene,” utilizing both area searches and K9 units to seek out any additional evidence in their investigation of the suspicious vehicle. At approximately 3 p.m. Thursday afternoon, police revealed the suspicious vehicle belonged to a woman who had just moved to the area, from Colorado. She reportedly told authorities she had parked her vehicle in the lot since Tuesday, due to parking restrictions at her new residence. She confirmed the little girl spotted in the vehicle in Dexter, Maine, was her daughter, and McDonald verified the plates matched the description of the details offered by the concerned caller in Maine.Portsmouth Police Chief Stephen Dubois answered a flurry of reporters' questions outside Portsmouth City Hall throughout the day. McDonald said the media frenzy was not anticipated by his department. “(The owner of vehicle) sort of laid out, not a comedy of errors, but a whole bunch of circumstances that led to this,” McDonald said. “But we're confident we cleared a tip for Colorado, so we're glad about that.”The Portsmouth Police Department worked jointly on their investigation with the Westminster, Colo., police department, Maine police departments and the FBI.The Westminster Police Department declined to comment on the case, or the discovery of the abandoned vehicle in New Hampshire. A spokeswoman asked those interested in the case to follow the department on Facebook and on Twitter (@westminsterpd) for further updates. “The investigation is ongoing and as soon as we have any information …, from tips around the country, … we'll comment on that when we know,” the spokeswoman said. Keaveny said he had heard the Colorado department had received upwards of 1,000 tips so far in its investigation.Those with tips or information related to the Ridgeway case are urged to call the Westminster Police Department tip line at 303-658-4336.
